A person who laced treats with sleeping medication and distributed them to minors at a summer camp in the region has confessed to sexual crimes against two children both between nine and ten.
The defendant was detained after eight youngsters and an older person fell ill at the location in the summer month.
The 76-year-old, from the Nottinghamshire area, confessed to a multiple criminal counts when he was present at Leicester Crown Court on recently.
Nevertheless, he refused to admit a single sexual charge he was accused of, which was involving a nine-year-old boy.
The defendant was kept in jail before a subsequent court date on 28 November.
'Candy game'
The prosecutor, presenting evidence, detailed the defendant's actions to the judicial body.
She stated his targets were children from difficult backgrounds who were participating in a summer camp which he managed.
Ruben conducted a "candy game" with the youngsters, the prosecutor explained, in which he would access the sleeping quarters when they were preparing to sleep and tell them to ingest treats "as quickly as they can".
She told the court the man had played this game with the young males "over an extended period", and children had earlier experienced illness the following morning.
She explained the man had been capable of justifying this repeatedly as the youngsters being "overexcited from fun", until his stepson had suspicions in recently.
Mrs Prior KC continued: "Recently" his stepchild had worries about what was going on, justifiably.
"They decided to have a look in the man's possessions."
The legal counsel said items including infant oil, ointment and syringes were discovered, and his family member contacted the law enforcement about his worries.
She said the defendant proceeded to engage in the "sweet game" with six boys that evening - that Saturday - and they were all ill the next day.
"Law enforcement" had not gone out by that time," she continued.
The regulatory agency, the police conduct office, earlier informed that it was investigating the police response of the events.
The legal representative said the youngsters were struggling to walk due to their sickness, so Ruben's stepson called the police once more.
She explained Ruben then played the "treat game" in a space of five minors.
